The same bidimensional scalar field displayed with 4 different color palettes [Le même champ scalaire bidimensionnel visualisé à l'aide de 4 palettes de couleurs différentes].




The upper right picture is the most informative one, for it is a one-to-one color mapping while the scalar field is as follows:
                    (y=511)   ff ff ... ff ff 00 00 ... 00 00
                    (y=510)   ff ff ... ff ff 00 00 ... 00 00
                    (y=509)   fe fe ... fe fe 01 01 ... 01 01
                    (y=508)   fe fe ... fe fe 01 01 ... 01 01
                    (y=507)   fd fd ... fd fd 02 02 ... 02 02
                    (y=506)   fd fd ... fd fd 02 02 ... 02 02
                      ...     .. .. ... .. .. .. .. ... .. ..

                    (y=257)   80 80 ... 80 80 7f 7f ... 7f 7f
                    (y=256)   80 80 ... 80 80 7f 7f ... 7f 7f
                    (y=255)   7f 7f ... 7f 7f 80 80 ... 80 80
                    (y=254)   7f 7f ... 7f 7f 80 80 ... 80 80
                      ...     .. .. ... .. .. .. .. ... .. ..
                      ...     .. .. ... .. .. .. .. ... .. ..

                    (y=005)   02 02 ... 02 02 fd fd ... fd fd
                    (y=004)   02 02 ... 02 02 fd fd ... fd fd
                    (y=003)   01 01 ... 01 01 fe fe ... fe fe
                    (y=002)   01 01 ... 01 01 fe fe ... fe fe
                    (y=001)   00 00 ... 00 00 ff ff ... ff ff
                    (y=000)   00 00 ... 00 00 ff ff ... ff ff
                          (x=000 ........ 255 256 ........ 511)
each point being coded using one byte (given as an hexadecimal value).

Figure "Profile of color palettes used" displays the profile of color palettes used.
